1 semicircle = 200 gon

Calculated in your browser

Conversion formula

gon = semicircle × 200

One semicircle equals 200 gradian. Multiply your value in semicircle by this factor to get gradian. For the reverse conversion, divide by the same factor.

Worked example

To convert 5 semicircle:
5 × 200 = 1,000 gon

About these measurements

An angle describes rotation between directions.

The base reference used here is the radian. One semicircle is 3.141592654 base units; one gradian is 0.01570796327 base units.

Important distinctions

A full turn is 360 degrees or 2π radians. Signed angles are permitted.

Precision

The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
